If you would like to solve the equation a^2 - 8*a + 12 = 0 for a, you can calculate this using the following steps:
a^2 - 8*a + 12 = 0
(a - 6) * (a - 2) = 0
1. a = 6
2. a = 2
The correct result would be B; 2, 6.
Answer:
$ 14.00
Step-by-step explanation:
10 · 1.75 = 17.50
17.50 · .20 = 3.5
17.50 - 3.50 = 14.00
good luck, i hope this helps :)
Jeremy's debt-to-credit ratio is 0.471.
<h3>What is debt-to-credit ratio?</h3>
debt-to-income ratio is the percentage of a consumer's monthly gross income that goes toward paying debts.
Here, Based on the given conditions,
formulate = Total debt / total credit limit
= 2355 / 5000
= 471/1000
Cross out the common factor: 471/1000
Round 471/1000 to the required place:: 0.471
Thus, Jeremy's debt-to-credit ratio is 0.471.

Answer:
18 gallons containing 20% solvent and 6 gallons containing 60% solvent
Step-by-step explanation:
the painter needs 24 gallons of paint containing 30% solvent = 7.2 gallons of solvent
let a = 20% solvent paint
let b = 60% solvent paint
a + b = 24
0.2a + 0.6b = 7.2
(replace a = 24 - b in the second equation)
a + b = 24
0.2(24 - b) + 0.6b = 7.2
4.8 - 0.2b + 0.6b = 7.2
0.4b = 7.2 - 4.8 = 2.4
b = 2.4 / 0.4 = 6
a = 24 - 6 = 18
Meaning there's only 1 real root, complete the square and you get the answer.
We're going to use this formula, so if x² = 4x² then x = 2x
and if y² = 1 then y = 1
Straight to formula
Because (2x+1)² is basically (2x+1)(2x+1), we get the same value of x.
So the answer is x = -1/2
(When D>0, there are 2 real roots.)
(When D=0, there are only 1 real root.)
(When D<0, there are no real roots, but 2 complex roots.)
